PM me who it is you have as your instructor and maybe I can give you some pointers. I'm at north, too.
I'm sorry you had a bad experience your first day. Everyone in my clinical group had a bad first day. Thankfully, though, we had a nice instructor so the bad experience had nothing to do with her, and we also had 2 students to a patient. I will say that after 3 courses, that day was still the hardest day I've had yet. All the rest of the days have been easier. I'm not saying some days weren't hard, because they were, but they've gotten easier. Nursing is dynamic. Its always changing and we have to be flexible. As your skills get better, so will your confidence and that will help.
I remember after my first day, I came home so exhausted- physically AND mentally. My husband took one look at me and said that it was ok if I didn't want to do nursing anymore. I guess by how I looked I looked as if maybe I didn't. But I told him that this is still what I want to do and I can't judge it off of one experience. I have to say, I think I hated clinicals in Process 1. All of them. Its no fun giving baths, changing linens and doing vitals and nothing else. In process 2, you start giving out meds. In GIGU, we start doing foleys and NG tubes and IV pushes. It gets better as you go along. Keep your head up, and even if you have to fake the confidence, then fake it. the patient, and your instructor, do not need to know you're nervous on the inside. If you get frazzled, ask a fellow student to help. Don't sweat it. Come up with a game plan on the order of how you want to do things. Go in, get your report from your nurse, introduce yourself to your patient, do your vitals and then your assessment. Try to get that done before breakfast. Then, you can write your notes while they are eating and when they are done, you can do your bath and linens. You will have patients who can wash themselves at times, so bring them their stuff and go in and change their sheets. It will get easier. After running behind that first day even though I had another student WITH me, I never thought I would be on time on my own. But I've been on my own since, and I have been doing just fine. I will say I think that was a horrible thing for your instructor to say (not so therapeutic as you just learned with communication, huh?). I have a pretty good idea who it is, too.
